ECMWF-AUX

The ECMWF-AUX data set is an intermediate product that contains the set of ancillary ECMWF state variable data interpolated to each CloudSat cloud profiling radar (CPR) bin. These data are required for input to the 2B-GEOPROF, 2B-CLDCLASS, 2B-TAU, and 2B-FLXHR algorithms. The ECMWF -AUX product is created by the Generic-AUX Interpolate-to-Reference algorithm. The input data is obtained from the AN-ECMWF dataset provided by the European Center for Medium-Range Weather Forecasts.

Changes/Updates in Algorithm Version P_R05 *

The source code was re-written in Python for improved accessibility and flexibility.

The calculation of the ECMWF pressure profile was corrected which will affect the vertical profile of every variable when compared to P_R04.

R04 of ECMWF-AUX, MODIS-AUX, & 2B-CLDCLASS released to General Science Community

September 17, 2007

Release 4 of ECMWF-AUX, MODIS-AUX, and 2B-CLDCLASS is now available to the General Science Community via the data ordering system.

All data users are asked to review the known issues page, on-line product specifications, and the summary of changes. If you have any questions concerning the ordering process, contact the DPC.

R04 available to the Science Team

July 19, 2007

Release 4 is now available to the CloudSat Science Team via the data ordering system. This release incorporates several improvements for the data products primarily driven by the development of a surface clutter reduction scheme in 1B-CPR. This affects all products by improving cloud detection near the Earth's surface. In addition, the profile overlap at the beginning and end of each granule has been removed. Granules now start with the first profile on or after the equator on a descending pass and end with the last profile before the equator on the next descending pass. Release 4 also includes the first release of the 2B-GEOPROF-LIDAR product.

This annoucement applies to the 1B-CPR, MODIS-AUX, ECMWF-AUX, 2B-GEOPROF, and 2B-GEOPROF-LIDAR products.
